Filtering Time
This shows the current smoothing time applied to the signal. Touch to change. This is
useful when there is a lot of noise or variation in the signal. The options are 0, 1, 2.5, 5,
7.5, 10 and Any seconds.
Slew Rate +
Current Positive Slew Rate filter setting. Sets the rate limit for large positive changes in
the ‘raw’ signal. This is helpful in applications where inherent irregularities in the signal
would tend to make it unstable, for example a mixer floor sensor where blades are
regularly passing the sensor face. The options are: None, Light, Medium, Heavy and Any.
Slew Rate –
Current Negative Slew Rate filter setting. Sets the rate limit for large negative changes in
the ‘raw’ signal. This is helpful in applications where inherent irregularities in the signal
would tend to make it unstable, for example a mixer floor sensor where blades are
regularly passing the sensor face. The options are: None, Light, Medium, Heavy and Any.
DSP Filter
The current setting of the Digital Signal Processing Filter. Touch to change. After the Slew
Rate filters the signal is passed through a digital filter which uses a special algorithm to
filter out the noise. There are six settings for the digital filter: Unused, Very Light, Light,
Medium, Heavy and Very Heavy.
Filter Include
When set, only Unscaled values above the set point will be included in the filtered output.

Unscaled 1 (only shown for selected sensors)
For sensors which support this option, this shows the current Measurement Mode used to
calculate the Unscaled 1 reading. Touch to change. For further details of the Measurement
Modes, refer to the Calibration and Configuration Guide HD0679.
